TL;DR

Unauthorised investment firm fraud — sometimes called boiler room fraud — costs UK consumers over £1 billion per year. Firms cold-call or contact victims via social media offering shares, bonds or alternative investments at prices below market value. The investments are worthless or non-existent. The FCA requires all UK investment firms to be authorised — check every firm at register.fca.org.uk before investing.

What is boiler room or unauthorised investment firm fraud?

Boiler room fraud gets its name from the high-pressure tactics used to sell worthless investments — traditionally operated from a room full of salespeople making cold calls. Modern versions operate via sophisticated websites, social media and messaging apps, but the fundamentals are the same: convincing victims to invest in shares, bonds, commodities, wine, carbon credits, land, storage units or other assets that are either worthless, non-existent or grossly overpriced.

The FCA estimates that UK consumers lose over £1 billion per year to investment fraud. The average loss per victim is £29,000 according to Action Fraud data. Victims are often experienced investors who are not typically considered vulnerable — the sophistication of the fraud is its most dangerous characteristic.

How unauthorised investment fraud works

Initial contact typically comes via cold call, email or social media. The fraudster presents a compelling investment case — often timing-sensitive, with claims of inside information or limited availability. A professional-looking prospectus or investment pack may be provided. The investment is described as low risk with guaranteed or assured returns. Small initial investments may perform well, generating fabricated account statements that encourage further investment. When the victim attempts to exit, they are told the investment is locked up, taxes must be paid first, or the market is temporarily unfavourable.

Common investment types used in fraud

Shares in unlisted companies — particularly those claiming to be about to float on a stock exchange — are a common vehicle. Alternative investments including wine, whisky, art, carbon credits, parking spaces, storage pods and overseas property are frequently used because they are harder for victims to value independently. Bonds from unregulated mini-bond issuers were common until FCA interventions. Cryptocurrency-linked investments now account for a growing proportion of cases.

Frequently asked questions

How do I check if an investment firm is FCA authorised?

Search the FCA Financial Services Register at register.fca.org.uk by firm name. Verify the firm is currently authorised (not cancelled or expired), that its authorisation covers investment activity, and that the contact details on the register match those given to you. Also check the FCA Warning List at fca.org.uk/consumers/warning-list.

What investments are covered by the FSCS?

Investments made through FCA-authorised firms are protected by the FSCS up to £85,000 per firm if the firm fails and cannot return assets. The FSCS does not cover investment losses due to market movements — only firm failure. Investments with unauthorised firms have no FSCS protection.

I was cold-called about an investment — what should I do?

Cold calling about investments was banned by the FCA in January 2019. Any unsolicited call about an investment is automatically suspicious. Do not give any personal or financial information. End the call. Report to Action Fraud on 0300 123 2040 and the FCA at fca.org.uk/consumers/report-scam.

The firm is registered at Companies House — does that mean it's legitimate?

No. Companies House registration confirms a company exists as a legal entity — it does not confirm FCA authorisation to provide investment services. Anyone can register a company at Companies House. FCA authorisation is a separate process requiring the firm to meet specific standards. Always check the FCA register, not just Companies House.

How do I report an unauthorised investment firm?

Report to Action Fraud at actionfraud.police.uk or 0300 123 2040. Report to the FCA at fca.org.uk/consumers/report-scam. The FCA prioritises reports about firms actively targeting UK consumers. Contact us at support@kaeltripton.com if a warning article on this site needs updating.
